Processes of the program and iRIClib subroutines

The I/O processings in solvers and grid generating programs are shown in Table 63 and Table 64 .

Table 63 I/O processings of solvers

Process
Opens a CGNS file
Sets up options
Reads calculation conditions
Reads grids
Reads boundary conditions
Reads geographic data (only when needed)
Outputs grids (only in cases when grid creation or re-division is performed)
Outputs time (or iteration count)
Outputs grids (only in cases when grid moves)
Outputs calculation results
Closes a CGNS file

Table 64 I/O processings of a grid generating program

Process
